Normal Operation
The air bag indicator is designed to illuminate for 6 (+/-2) seconds when the ignition switch is turned to the RUN position. This initial 6 seconds of illumination is considered normal operation and is called prove out of the air bag indicator. The air bag indicator is then used to warn the driver if there is a fault in the air bag Supplemental Restraint System (SRS).

The Restraints Control Module (RCM) monitors the air bag indicator for open and short to ground conditions. If the RCM detects an open or short to ground condition on the air bag indicator circuit, it will store a Diagnostic Trouble Code (DTC) B1869 in memory.

If the RCM detects an air bag indicator failure in addition to another SRS failure, the RCM will send a signal to the instrument cluster to produce five sets of five tone bursts.

Possible Causes
An air bag indicator inoperative condition can be caused by:
^ damaged wiring on circuit 608 (BK/YE).
^ a damaged or burned out air bag indicator.
^ an instrument cluster malfunction.
^ a damaged RCM.
